Well, they gathered 43k on a mere promise from the cRPG community within like two weeks at the start of 2012. There were still some people that missed the limited time this original investment option was open and they were pretty vocal about it. I guess they kinda expected a bigger initial bump from the cRPG community, which would have put the funding on a much more promising track. I did too but it is easy to forget that cRPG was about twice as active in 2012.
I still think there are huge groups that could be interested that haven't really been reached, but it is pretty tough to gain exposure in a good way and Kickstarter is in a huge slump as far as games by unknown indie developers go. Aside from that I think they might have fired a little early, with lots of the core gameplay being very work in progress. Chivalry looked like a pretty far along game when its Kickstarter started. To appeal to those already familiar with the genre, it is critical to demonstrate why this gameplay is as good or better than other Medieval action games.
Well, in any case, they got their name out there even if the Kickstarter fails. This game will be finished without a doubt at some point, perhaps if they can re-Kickstarter with a more far along product, they'll fare better in the future. Hoping for a miracle still though, I know these guys are making sacrifices to work on this.
